Resolution and interlacing
Two of the elements that determine the quality of a TV picture are resolution and interlacing.
● Resolution : For TV equipment and broadcasts, resolution is defined by the number of
horizontal lines displayed to make up each frame of a video image.
The more lines of resolution used to draw each frame of video, the more detailed
and sharp the picture will be. Standard TV resolution uses 576 horizontal lines to
make up each frame of video.
HDTV uses either 720 lines, or 1080 lines to make each video frame.
● Interlacing : When TVs display video, they display a new video frame at a rate that is faster
than your eye can see (from 24 to 60 frames per second, depending on the
TV and broadcast). Interlacing refers to whether each of those frames contains
all of the lines of video for each frame or every other line. Interlaced signals take
every other line from 2 frames of video (each lasting 1/60th of a second), and
combine them into one frame lasting 1/30th of a second. In this way, interlacing
tricks your eye into thinking it is seeing twice the resolution that is actually being
displayed.
In non-interlaced video, (referred to as progressive scan video), video frames are
displayed every 1/60th of a second containing all of the lines of video information
for each frame.
The specifications for video resolutions are usually stated by giving the number of horizontal lines,
followed by either the letter i, for interlaced video, or p for progressive scan video. Most standard
TV broadcasts are 576i (576 lines of interlaced video resolution).
